Previous studies indicate that the southward migration through Oregon lasts about two months (Herzing and Mate 1984). However, 90% of the whales migrated past Yaquina Head between December 19 and January 23. The northward migration through Oregon is divided in two phases. Phase A, which comprises adults without calves, begins during the last week of February with a peak in mid-March.
In the spring, harp seals migrate southward, assembling in large groups to breed near the Newfoundland and Norwegian coasts. During late February and early March, thousands of harp seal females gather to deliver their babies on the White Sea ice (Pagophilus.org 2001).
